  • Thread control in textile machines
    Patent number: 4331008
    Abstract: A thread monitor for use in textile machines monitors thread tension (i.e. to detect thread breakage or relaxation) and the presence of knots in the thread. If either is detected the monitor issues a signal and shuts down the associated textile machine. The device can be adjusted for different thread tensions, different thread thicknesses and different knot sizes. To prevent difficulties due to electrostatic charging the main elements of the monitor are connected to a grounding terminal.
